Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

A total of 550 patients with stable angina (40-70% stenosis) tested by coronary CT angiography (CCTA) and single photon emission computed tomography (SPECT) and coronary angiography (CAG) within 3 months were retrospectively recruited from 2005 to 2015 and follow up to 5 years. A new hybrid software was used to analysis the image data.
